commit 4da3dca651bc2b77fb3459b2e14eb00674b69af7 Author: Sven Eckelmann sven@open-mesh.com Date: Wed May 22 04:55:21 2013 -0700

alfred: Set length of dataset to zero after freeing

The buffer allocation can fail for malloc and the length of the data would still be != 0. Resetting it 0 should reduce the chance of an inconsistent view on the stored data.
